Unique Melody 3DT Review

Sound Quality

The frequency chart that UM provides makes an impression of an extreme v-shape response. In reality that’s not the case but overall the 3DT gives a slight V, which is not extreme but acceptable to me. The 3DT sounds very energetic, dynamic, and forward at times, and it’s not a shy IEM whatsoever.

I’m normally not a fan of a v-shaped sound, even a slight one. But it’s not about my personal preference of course. Some people would love this presentation with certain genres. But what matters to me is the technical performance of the IEM. And that’s where I found the 3DT successful for its price. This actually is a price/performance IEM, especially with its present price.

Bass

Two dynamic drivers are reserved for the bass region alone, and you might think that the 3DT is a bass monster. Well, it’s not even close to that. The lower region is very controlled, tight and it has a very good pace. While it can give the kick and rumble when needed, it’s never bloated, never aggressive, or out of control. The bass response is very disciplined, it doesn’t cloud the mid-range or lower mids specifically, and it even makes you want more quantity with EDM songs.

So yes, the Unique Melody 3DT is not actually a very bassy IEM. It’s like it lies in between the DD and BA bass. I don’t know how they managed to achieve this though. It’s quick like a BA driver bass, but it contains the air and kick of a dynamic driver. There isn’t any mid-bass hump noticeable, and the decay of the bass is excellent.

This reminded me of the old UM Maverick’s bass response. Overall the bass doesn’t go very deep and it has a mid-bass focus, but the texture is great. Overall the 3DT has an amazingly good bass performance for this price.

Mids

I expected recessed mids with the 3DT, and although that is the case, it doesn’t bother me much. The lower mid-region takes a small step back in the sound, and that makes the upper mid-region a bit elevated as a result. This creates a very energetic and clear presentation overall.

Yet, the lower mids are not absent and you can hear the foundation of the thick instruments with ease. I think UM chose to go with a very clean and crisp presentation so they boosted up the upper mids and lower treble a bit, but the IEM doesn’t miss the full response entirely. The mids still have good timbre with excellent definition. Especially female vocals are exceptional here, so I recommend you to listen to some divas with this one.

So this teaches us that, a v-shaped sound can still be very good and it all depends on the tuning itself. I can still say that this is not my type of presentation. But the key thing is, I enjoyed it. I’m not going to criticize it just because it’s not my sound. The vocals and instruments have great tone and dynamism. You’re not going to get bored with this IEM

Treble

The treble section is just as good as the bass region. There’s a good extension here with a good amount of air. The lower treble region is a bit elevated as a continuation of the upper mids, and that’s only natural to me. Otherwise, it would’ve been a very inconsistent presentation. The lower treble boost is not aggressive and there’s no problem regarding sibilance or peaks.

For the price, the treble section has excellent detail retrieval, control, and articulation. Tonality on the treble area is a little thinner though and it can be altered by the source, but it’s still coherent and assists the imaging capabilities very well. The upper treble section is smooth and it’s not peaky at all. In fact, I can say that the upper treble section is quite forgiving and relaxed.
